Airmar B275C-LHW Transducer With 2 - 9-Pin Navico MMC

The Airmar B275C-LHW Transducer with 2 – 9-Pin Navico MMC is the workhorse sounder for serious anglers and boaters who demand reliable, real-time bottom imaging and fish detection. Built for saltwater and freshwater applications, this transducer integrates seamlessly with Navico chartplotters and multifunction displays, giving you the situational awareness needed to locate structure, depth changes, and feeding activity. Whether you're running coastal flats, deep offshore waters, or inland reservoirs, this transducer delivers the precision sonar data that separates productive days on the water from wasted fuel and hours.

The B275C-LHW employs advanced dual-frequency sonar technology with exceptional sensitivity across both shallow and deep-water scenarios. Its through-hull hull design minimizes turbulence and provides stable signal transmission, while the dual 9-pin Navico MMC connections ensure redundancy and allow you to run independent sonar feeds to multiple displays or backup systems—critical for tournament anglers and professional charters. The transducer's rugged construction withstands saltwater corrosion and mechanical stress from rough seas, and its precision calibration delivers crisp sonar imagery with minimal water-column noise, allowing you to distinguish baitfish schools from structure with confidence.

This transducer is ideal for anglers running Navico-compatible systems—Lowrance, Simrad, and B&G displays—and works with both legacy and modern chartplotters. Installation requires a through-hull mount, and proper sealing is essential to prevent water intrusion and maintain sonar performance. At 25 pounds, it demands a secure transom or hull bracket and careful cable routing to avoid chafe and interference. For boats already equipped with Navico electronics, the dual 9-pin connections streamline integration and eliminate the need for adapters, reducing installation time and potential failure points on the water.
